vkGetShaderInfoAMD

Information about a particular shader that has been compiled as part of a pipeline object can be extracted by calling:

VkResult vkGetShaderInfoAMD(
    VkDevice device,
    VkPipeline pipeline,
    VkShaderStageFlagBits shaderStage,
    VkShaderInfoTypeAMD infoType,
    size_t* pInfoSize,
    void* pInfo);

• device is the device that created pipeline.
• pipeline is the target of the query.
• shaderStage is a VkShaderStageFlagBits specifying the particular shader within the pipeline about which information is being queried.
• infoType describes what kind of information is being queried.
• pInfoSize is a pointer to a value related to the amount of data the query returns, as described below.
• pInfo is either NULL or a pointer to a buffer.

If pInfo is NULL, then the maximum size of the information that can be retrieved about the shader, in bytes, is returned in pInfoSize. Otherwise, pInfoSize must point to a variable set by the application to the size of the buffer, in bytes, pointed to by pInfo, and on return the variable is overwritten with the amount of data actually written to pInfo. If pInfoSize is less than the maximum size that can be retrieved by the pipeline cache, then at most pInfoSize bytes will be written to pInfo, and VK_INCOMPLETE will be returned, instead of VK_SUCCESS, to indicate that not all required of the pipeline cache was returned.

Not all information is available for every shader and implementations may not support all kinds of information for any shader. When a certain type of information is unavailable, the function returns VK_ERROR_FEATURE_NOT_PRESENT.

If information is successfully and fully queried, the function will return VK_SUCCESS.

For infoType VK_SHADER_INFO_TYPE_STATISTICS_AMD, a VkShaderStatisticsInfoAMD structure will be written to the buffer pointed to by pInfo. This structure will be populated with statistics regarding the physical device resources used by that shader along with other miscellaneous information and is described in further detail below.

For infoType VK_SHADER_INFO_TYPE_DISASSEMBLY_AMD, pInfo is a pointer to a null-terminated UTF-8 string containing human-readable disassembly. The exact formatting and contents of the disassembly string are vendor-specific.

The formatting and contents of all other types of information, including infoType VK_SHADER_INFO_TYPE_BINARY_AMD, are left to the vendor and are not further specified by this extension.
